Reheating of Brownie - A/B Testing

Yesterday, for our weekly flat dinner, I made my first brownie dessert. It was great, but impossible to finish, thus layering chocolate aroma in the fridge for the next few days.

Hot piping brownie taste best with decadent ice-cream, and I found two ways to reheat:

Oven
Microwave
Starting with a hypothesis “Oven reheating of brownie taste better then Microwave”, I sliced two cubes off the brownie tray:
Reheating one in the oven for 10 mins
And the other in the Microwave for 15 seconds

Ensuring a fair competition, oven reheated brownie was prepared earlier so that both brownies would be ready at the same time.

Hearing a detectable crack through the crust as I chomped through the brownie (oven reheated), I tasted the dense brownie but found it a bit dry. I went to rinse my mouth after the first chomp and got ready for my next.

Burnt wet smell greeted me as I bite my way through the other.

Scooping the Apricot ice-cream on the brownie, I stared into the horizon ready to tuck in.

Self-Service BI Users

Summary

Recently I had some discussion with my colleagues about the users for Self Service BI. I believe that there are three main types of users for Self-Service BI.

What is Self-Service BI?

Self-Service BI is implemented to allow user to easily drill down, drill through charts, tables and maps to understand data in multiple dimensions in a quick and easy fashion.

It can be refreshed on a periodic basis (Eg. Realtime, Daily and Monthly Refresh)
It should not cover all the use cases, and should only cover 80% of the requirements. The rest of the requirements could be covered off in another separate report.

Graphics (Eg. Charts, table and maps) can be be easily manipulated by an individual with some basic understanding of how a database works without any actual coding required.

Users of Self-Service BI Tool

Users	Details	User Goal	Possible User Roles
Consumer - Decision	Using Data to Make Decision	Want somebody to help to use data to answer questions that they have, or want to track if everything is on track on a one-page view as they do not have the time to figure out how to operate the Self-Service BI tool.	Management Team
Consumer - Discover	Using Data to Discover Insights	Will interact with the data by drilling down, through charts, tables and maps that are pre-designed by Analyst or Data Scientist.	Middle Management and all other employees (Not inclusive of Analyst and Data Scientist)
Recommend / Consumer - Discover	Manipulate Data to Discover Insights	Wanted to be able to combine multiple data sets from one or more sources, and manipulate the data to recommend / discover insights. The manipulation can come from technical transformation of data, or / and the aesthetics visuals via the Charts, Tables and Maps to visualize the information.	Analyst, Data Scientist and anybody who has a technical bent
